COMPOSITION FOR INCREASING DOPAMINE AND NOREPINEPHILIN CONTENT WITHIN NEUROSYNAPSE

摘要

A material and composition are provided for regulating dopamine or norepinephrine levels in neuronal synapses. The levels of dopamine and/or norepinephrine are regulated by administering a neutral amino acid composition to a patient wherein increased or decreased brain levels of dopamine and/or norepinephrine are effected when the composition contains increased or decreased amounts of tyrosine and/or phenylalanine. Increased or decreased brain levels of serotonin are obtained when the amino acid composition contains increased or decreased amounts of tryptophan. The neutral amino acid composition can be administered alone or concomitantly with a drug which increases or decreases dopaminergic or noradrenergic neurotransmission.
